219 billion tonnes of Antarctic ice lost annually

219 billion tonnes of Antarctic ice lost annually

"The continent is causing sea levels to rise faster today than at any time in the past 25 years", one of the study's lead authors, Andrew Shepherd of the University of Leeds, said in a news release.

West Antarctica lost 159 billion tons of ice a year from 2012 through 2017, compared with just 65 billion tons from 2002 through 2007.

A team of researchers on the German research icebreaker Polarstern have successfully mapped an area of the seafloor previously covered by ice.

DeConto said, "Emerging science is pointing to more extreme worst-case scenarios with regards to sea level rise from Antarctica, but the good news is that a reduction in emissions, in line with the aspirations of the Paris Climate Agreement, dramatically reduces the risk of flooding our coastlines in future decades and centuries". And it has grave implications for low-lying countries such as the Solomon Islands and the Maldives, suggesting they have less time to construct future defences against the rising ocean. He said, "Under natural conditions we don't expect the ice sheet to lose ice at all".

The differences between the studies are reconciled to produce the most definitive possible set of data.

Recent work by Rob DeConto, the 2016 victor of the Tinker prize and professor of geosciences at the University of Massachusetts Amherst, includes findings in a 2016 paper also in Nature that highlights the potential for Antarctica to contribute much more sea level rise to the world's oceans than previously considered. The current fast pace at which this ice is melting is estimated to trigger a six-inch rise (15 centimeters) in global sea levels by the end of the century. Meanwhile, the Financial Times finds its own angle to the story: "The natural gas industry grew a year ago at the fastest rate since the immediate aftermath of the financial crisis, led by a surge in Chinese demand, which also helped to propel growth in energy consumption globally, according to energy major BP..." Nearly 200 countries agreed on the need to cut greenhouse gas emissions at the signing of the Paris climate agreement, and committed to keeping global temperatures "well below" 2°C above pre-industrial times.

It can be easy to overlook the monstrous scale of the Antarctic ice sheet.

Already floating, ice shelves breaking off into icebergs do not add to sea level.

Washington D.C. [USA]: Antarctica's ice loss has tripled since 2012, according to a study. "We share responsibility for our climate system and need to increase our collective climate ambition".

"We have long suspected that changes in Earth's climate will affect the polar ice sheets", said Professor Shepherd.

Earlier studies of the East Antarctic Ice Sheet indicated that some marine-based portions of the ice sheet and its neighboring West Antarctic Ice Sheet retreated during the Pliocene. But what concerns scientists is the balance of how much snow and ice accumulates in a given year versus the amount that is lost. Technology can also be redesigned to rejuvenate the environment.B ut the most important step which can be taken regarding pollution is that the policymakers make it a priority to keep an environment check and find better policies which could help us to live in a stable environment.

The discovery comes after the global research team, from Australia, the United States and New Zealand, combined satellite images and surface and ocean wave data with modelling, to analyse five major ice shelf disintegrations, between 1995 and 2009.
